The Campton police chief said at about 12:40 p.m. Thursday, the box truck, operated by Wayne Rix, 65, of Rochester damaged a number of wooden cross beams when it drove across the bridge.

Police said the Blair Bridge has a height limit of 8 feet and the box truck was too tall for it, Rix told officers he was driving and Route 175 and was following detour signs that led him the bridge. Police said charges are pending against Rix.

The Blair Bridge recently underwent a year-long, $1.5 million renovation. Inspectors said the bridge is structurally sound and is open to traffic, but will need to undergo repairs after the Labor Day weekend.
